if the following code is commented out from visualc.hpp the standard streaming operators become available for mersenne_twister - and they seem to work fine. is this a bug or have i just been fortunate in my experimentation? #if _MSC_VER <= 1310 # define BOOST_NO_MEMBER_TEMPLATE_FRIENDS #endif ian whittley

I admit to being a little surprised by that myself, I'll look into it... OK it was disabled by Beman Dawes with the comment "See format_test1 for example of why needed", and this test case does indeed fail if we undef that macro - it uses friend functions that are namespace qualified and very few compilers currently support that unfortunately.

replacing the guards around the streaming operators in mersenne_twister and lagged_fibonacci with: #if !defined(BOOST_NO_MEMBER_TEMPLATE_FRIENDS) || (_MSC_VER >= 1310) allows the code for both classes to compile under VC7.1. perhaps we need finer grained guard macros? ian
